Your physic is legendary and impressive even by the standards of your robust peers.
Prerequisite(s): 1d12 Hit Dice.
Benefits: When you gain a new level and make your roll for hit points you may use 2d6 (adding the results together) rather than 1d12. Rolling for new hit points in this way does not increase your total Hit Dice, but simply increases the chances of gaining a higher result.
